软件结构级上的需求变化处理

Variant Handlings at an Architectural Level of Design

为处理需求变化 ,提出一种基于软件结构引入技术的变化处理机制 (VariantHandlingBasedonSoftwareArchitectureIntroduction ,VHBSAI)和它的 4个具体的与软件开发相关的实施步骤 (需求变化的分析和识别 ,变化对象的转化 ,软件结构的引入 ,软件结构的调整 ) ,以达到对其他变化处理技术进行指导 ,以及以模块上的操作手段 ,有效地进行软件系统维护 .VHBSAI为软件系统生命周期、开发效益等问题提供了新的解决方法 .

In contrary to the study of software architecture based on domain engineering, variant handling based on software architecture introduction (VHBSAI) is at a higher level of design and applicable to most requirement analysis techniques. Moreover, to improve effectiveness and productivity of software development this promising approach to variant handlings at an architectural level of design enables guiding other variant handling techniques and preparing for the effective maintenance activities in software development. This method is decoupled into four stages: analysis and identification of requirement variants, variant objects transformation, software architecture introduction, and modification of software architecture. One successful case of VHBSAI in chess game server is presented.
